macOS 15 Sequoia on Unsupported Macs Thread

[seaweed_coast]

Hello nice people,
Please help me with this almost off-topic question;

Tomorrow we will probably receive a new M4 imac at home as a new companion of the existing Macbook Pro 2015 running on OCLP and MacOS 15.2.

Can I safely use the Migration Assistant-app on the new iMac to switch from this OCLP installed MacBook to M4?
Or will I definitely cause problems with this?

Many thanks for the help from Amsterdam.

Yes, uninstall root patch first.

Yes, uninstall root patch first.

I have only ever needed to uninstall root patch on the target (migration destination). Is there guidance to uninstall root patches from the source before migrating?

The M4 target will not be patched. But I think I can succeed by uninstalling OCLP on the "old" MacBook first as source. Thanks

I'm wondering why people activate the Filevault.

Are you afraid of sensitive data on your boxes or paranoia?

or afraid of the NSA or FBI searching through data on your damn private boxes???

People have sensitive data like account numbers or passwords or the answers to dumb security questions they needed to answer for various accounts just sitting on their computers. If someone steals your laptop and goes hunting for stuff are you so sure they won't find something that might create a huge hassle if you have to clean it up after the fact?

Some of my clients have had computers stolen out of their offices before. IMO, it's just good sense to use filevault, just like it's good sense to lock your doors. Probably nothing is going to happen, but if it does you will probably be glad you used it.

As long as unpatched gives you some semblance of networking, yes.

2.1.1 is a bug fix release for 2.1.0

And 2.1.2 for 2.1.1

>> And 2.1.2 for 2.1.1

The following is for any who are interested in troubles with OCLP 2.1.2 -

I was fine under Monterey and Sequoia(so far) in separate SATA SSDs with OCLP 2.1.1

Win11 installed and working with DCS world, on a NVME, on a PCIe-NVME card. Great!

2.1.2 however, has stopped my Asus BT400 USB dongle from working, bluetooth settings won't turn on
and menu says it is on.

And I get freezes at any time, with multiple apps open in Monterey, requiring power off and then
fresh boot. And sometimes, 4 x Cmd Opt P R nvram reset

I spent all day trying a fresh Sequoia 15.1 install with OCLP 2.1.2 onto a blank 1 Tb SSD, it got as far as "migrate has succeeded" and then looped and looped endlessly - 4 times I tried that install.

I downgraded OCLP from 2.1.2 to 2.1.1 or and all is well again - Monterey on an SSD, Sequoia on an SSD and Win 11 on the NVME. Bluetooth dongle working.

 

[ronton3]

I now have Monterey on the internal HD, on the external SSD I have the latest OCLP/Sequoia.

I've been curious about what would happen if I clicked on the EXE disc that appears when I press the space bar after the startup discs come up at login. Now no matter what I try I can not get the external disc with OCLP/Sequoia to show up at login. Now on regular startup it is just the Apple logo and the the progress bar, no startup disc appears. If I hold the option key only the internal disc and the network choice shows up. I have reset SMC and NVRAM. Any advice will be welcome.

Finally problem solved, i can't remember all the things I did, but finally with the option key: internal, EFI boot and external showed up. The first time I clicked external that did not work, I tried again and clicked EFI boot and external did boot. I notice now that when the progress bar is closer to the logo it boots in Monterey and when the progress is nearer the bottom it boots in OCLP/External.

I will not experiment with EXE again.

 

[roronl]

As long as unpatched gives you some semblance of networking, yes.

With a ethernet cable connected between old and new and Migration Assistant it was a swift success.
Thanks.

So far, my MacBookPro14,2 runs perfectly with OCLP and Sequoia.

But I had to learn the hard way.

I upgraded directly OTA from Ventura to Sequoia, but after that I had to deal with some difficulties and problems:

I could no longer log into Messages and Facetime. Unlocking the Mac with an Apple Watch could not be set up (the option was not even available in the system settings). iCloud, Find My ... and AirDrop were very tricky. In addition, sleep mode did not work. If I closed the laptop overnight and opened it again in the morning, the Mac restarted completely.

All problems disappeared after a clean installation. But when I restored my data with a Time Machine backup, the problems described above also returned.

What finally worked for me: A clean install with a manual restore of my data and applications.

The computer now feels like new, it's running fantastically so far!

Hello,

I just managed to update my new MBP mid 2012. I first made update over new Catalina on original disk then updated over my old Catalina on disk from old Mac but on any of them I was not able to get Airdrop working properly. Or even it is nearly funny how it works.
I have two phones. SE and SE 2020 (iOS 17) when SE 2020 and Mac are active I see nothing. When I unlock old SE it appears on phone and Mac. When I trigger Airdrop sharing on old SE both phones appear on Mac. But Mac never appears on any of Phones.

Would anyone has clue what to try? It is one of reasons I got newer Mac besides 15" screen.

Otherwise runs fast and great.

The following problem, OCLP 2.1.2 and 15.2 Beta (24C5073e)
when the iMac (5K, 27-inch, 2017) is in sleep mode and I try to wake it up with the magic mouse, the screen goes black and freezes and the screen only stays black afterwards.

This happened after updating OCLP from 2.1.1 to 2.1.2, I reset it to 2.1.1 but had the same problem afterwards, can anyone help? Would be nice.

 

[ranmandx]

Hey all.

I got to say opencore legacy patcher has made me hold off on upgrading my mac. But i have one issue with Sequoia and Macbook Pro 13,3 (late 2016 touchbar)

Everything works really well EXCEPT facetime. I am unable to make a facetime call or answer one successfully. Continuity camera works fine even. I installed opencore and sonoma on an external SSD to try and it seems to be working quite well and facetime and continuity camera work. To everyone who was saying T1 chip doesn't work on sequoia i have to say my touchbar is working fine and touch id is working fine as well. I am unable to add cards to apple pay on my mac but using apple pay just requires confirmation on my watch or phone. If i can get facetime to work i would be super happy.

One other issue which is also on sonoma so i think it's something entirely different. NordVPN constantly from waking up from sleep has popups that there is no network connection and i got to clear it all the time.

If the recommendation is to downgrade and use sonoma instead i don't mind staying on sequoia until it works if facetime is the only thing i am sacrificing for the time being.

Running opencore 2.1.2 and MacOS 15.1

The built in cameras work on all my MacBooks and iMacs, but when I have the mini hooked to a Thunderbolt Display I get nothing. Do I still need to tccplus the camera?

I downgraded OCLP from 2.1.2 to 2.1.1 or and all is well again - Monterey on an SSD, Sequoia on an SSD and Win 11 on the NVME. Bluetooth dongle working.

A wrinkle: I have been quick to attribute the above issues to OCLP 2.1.2. Other things got me thinking. I had a 20Gb partition on the Sequoia SSD with a Sequoia installer on it as others have suggested. I also had OCLP on The Monterey SSD, and the Sequoia SSD and well as this Sequoia Installer partition.

So three instances, each of which I diligently updated to 2.1.2.

Too many? Im going for keep it simple stupid and make the Monterey SSD the OCLP (edit: 2.1.1) disk and anything else sans OCLP.

The time saved by having a seperate 20gb installer partition is negated when I have to spend a day faffing around to rectify mistakes so I'm gonna use USB sticks for the foreseeable.

 

[ronton3]

I am thinking about testing the speed of my recent SDK SSD, and some others, I see iBoysoft DiskGeeker, and wonder if it is the best option or is there something less expensive, and would it interfere with OCLP?

Updating a spare 2017 MacBook Air to Sequoia 15.1 from a flawless Sonoma 14.7.1 install. I’m still amazed it works at all.

If my 2020 M1 MacBook Pro breaks (already suddenly no camera, no ambient light sensor, and an only once failing trackpad on left click—no resale value), I want an immediate fallback for work.

UPDATE: installed perfectly; but it is running hotter than Sonoma. Quite usable, but more fan noise.

 

[Sven G]

After reading through that thread, it seems like it's not OpenCore specific even though there are OpenCore users there. Someone on a Native M3 Machine reported the same issue.

Yes, probably something more Sequoia-related, as it began to happen after upgrading from Sonoma to Sequoia. We’ll see if they can fix it…

Same here but I have two more issues:
1. Messages app works laggy, sometimes it crashes, sometimes it takes about 10 minutes to launch but then app freezes again
2. AirDrop does not see my iPhone

 

[Sven G]

Hi @Sven G ! On my iMac (see in the signature) I have enabled FileVault from Catalina all the way to Sequoia and this is the first time I've heard of this oddity.
Usually, with past Mac OS Xs, all you had to do was delete the Preferences files.
You can try searching the System (e.g., in the root’s Library, in the $Home’s Library and in /etc/) and see if you notice any files that you can remove so that the System, then, recreates them the right way.
I know it's not simple, but as a simple Nerd that's what I would try before giving up and reinstalling everything; of course first normally, i.e. rewriting just macOS and then reinstalling everything from scratch if the problem doesn't resolve.

Hi, Enzo: it looks like an SMC + “deep” (5-bong) NVRAM reset fixed the dual login issue (which anyway manifested itself only on cold boots): let’s hope this will be a sufficient fix…

 

[trifero]

I´afraid we are getting closer to the point where OCLP will get less and less of the new features, cause it´s normal.

Kept my Monterey on my Mac Pro 5,1. Rock solid. Said this, I can´t express how impressed I am with my new Macbook Pro 16" M4. Though I LOVE my old macs, it makes so difficult to return to them.

 

[amaze1499]

Do you really think that deep NVRAM reset is a thing? It’s a chip. You reset it once and then it’s back to default settings. Why would you try that five times? Just asking out of curiosity.

 

[Sven G]

IIRC, someone - here or elsewhere - said that it could be more effective to reset up to 4-5 times in sequence: but probably just one or 2-3 times might be sufficient. Also in the classic days, it was often said that up to 3 times was better; but who knows, anyway: maybe only urban legends…
